First paragraph of their statement I think better summarizes their reasoning:

> In view of increasing geopolitical unrest, DNB is strengthening its crisis preparedness. Improving the liquidity and tradability of the Dutch gold reserves is part of these preparations. Moreover, a more balanced distribution of these reserves between North America, the United Kingdom and the Netherlands helps to spread risks and will make them more readily available for use in a crisis situation.

The goal is to make these reserves more liquid in the event of a geopolitical crisis. It’s easy to say that Trump was a factor in this decision given that he has been the cause of one geopolitical crisis after another. That hypothetical crisis doesn’t have to directly involve the Netherlands for this to make sense. For example, the price of oil shot way up because Trump decided to poke Iran and having more liquid reserves could make responding to that easier.

> It’s easy to say that Trump was a factor in this decision

I don't disagree with that. (I mentioned Iran, a crisis that was precipitated by the current administration.)

I disagree with "Experts say that rhetoric appears inherently related to the abrasiveness of the Trump administration towards traditional allies" and "Having those reserves in the United States is a potential vulnerability...You can absolutely imagine a scenario where, for whatever reason, the Trump administration decides to hold onto them" etc.
